While most attempts to classify the different types of zombies limit their analysis to fast vs. slow, alive vs. dead, Jason Thompson's massive zombie taxonomy map goes far beyond that, cataloguing more than 350 different types of zombie.

Thompson is an obsessive fan of the of the horror genre—we've previously highlighted his comics adapting H.P. Lovecraft's Dream Cycle and his webcomic The Stiff—and here he puts that obsession to great use. Drawn in the style of a vintage medical chart, this map classifies zombies from numerous books, movies, comics, video games, and TV shows, from literary proto-zombies to modern zombie romantic comedies. It's fun to get lost looking through this chart. (Be sure to click "expand" on the image below in order to read all the type.)
